Two-dimensional (2D) covalent organic frameworks (COFs) are an emerging class of promising 2D materials with high crystallinity and tunable structures. However, the low electrical conductivity impedes their applications in electronics optoelectronics. Integrating large π-conjugated building blocks into lattices to enhance efficient π-stacking chemical doping is effective way improve COFs. Herein, two nonplanar COFs kagome (DHP-COF) rhombus (c-HBC-COF) have been designed synthesized from...
We show that covalent functionalization of carbon nanotubes (CNTs) via 1,3-dipolar cycloaddition is a powerful method for enhancing the ability to process CNTs and facilitating preparation hybrid composites, which achieved solely by mixing. were functionalized with phenol groups, providing stable dispersions in range polar solvents, including water. Additionally, could easily be combined polymers layered aluminosilicate clay minerals give homogeneous, coherent, transparent CNT thin films gels.
Despite the increasing interest of scientific community in carbon nanotubes and graphene, fullerene C60 still plays an important role family nanocarbons. A quarter a century research on fullerenes has been dedicated to understanding way produce stable, well-characterized highly soluble derivatives, which retain original properties C60. The applications wide number fields, especially new materials design, have enriched literature with fascinating examples where are directly involved. We...
Abstract Twisted two‐dimensional aromatic frameworks have been prepared by overcrowding the nodes with bulky and rigid substituents. The highly distorted framework alternating out‐of‐plane substituents results in diminished interlayer interactions that favor exfoliation dispersion of individual layers organic media.
The properties of graphene nanoribbons are highly dependent on structural variables such as width, length, edge structure, and heteroatom doping. Therefore, atomic precision over all these is necessary for establishing their fundamental exploring potential applications. An iterative approach presented that assembles a small carefully designed molecular building block into monodisperse N-doped with different lengths. To showcase this approach, the synthesis characterisation series constituted...
A high degree of crystallinity is an essential aspect in two-dimensional covalent organic frameworks, as many properties depend strongly on the structural arrangement different layers and their constituents. We introduce herein a new design strategy based core-twisted polycyclic aromatic hydrocarbon rigid nodes that give rise to framework with wavy honeycomb (chairlike) lattice. The concave-convex self-complementarity lattice guides stacking into highly stable ordered allows full 3D analysis...
Abstract Three‐dimensional covalent organic frameworks (3D COFs) with a pcu topology have been obtained from distorted polycyclic aromatic hydrocarbons acting as triangular antiprismatic ( D 3 d ) nodes. Such 3D COFs are six‐fold interpenetrated the result of interframework π‐stacking, which enable charge transport properties that not expected for COFs.
The synthesis of three molecular nanoribbons with a twisted aromatic framework is described. largest one shows 53 linearly fused rings backbone (12.9 nm) and 322 conjugated atoms in its core (C296N24S2). This new family extremely high molar absorptivities, reaching 986 100 M–1 cm–1, red-emitting properties.
Molecular conformation has an important role in chemistry and materials science. nanoribbons can adopt chiral twisted helical conformations. However, the synthesis of single-handed helically molecular still represents a considerable challenge. Herein, we describe asymmetric approach to induce helicity with excellent degree conformational discrimination. The induction is result strain generated by fusing two oversized rings propagation that along nanoribbon's backbone.
Two-dimensional conjugated metal-organic frameworks (2D c-MOFs) have emerged as a new class of crystalline layered conducting materials that hold significant promise for applications in electronics and spintronics. However, current 2D c-MOFs are mainly made from organic planar ligands, whereas constructed by curved or twisted ligands featuring novel orbital structures electronic states remain less developed. Herein, we report Cu-catecholate wavy c-MOF (Cu3(HFcHBC)2) based on fluorinated...
